Post Drive Migration Questions

Hi all,

We just did a hard drive migration from a RS3617xs+ to a RS3621xs+ per the relevant support article from synology.

Everything went as expected, we were prompted to migrate settings after moving drives and first booting up new one.

After the initial DSM install, the drives show as ‘unverified’ in storage manager which I believe is normal.

But then the unit alerted about storage degradation and 1 (of the 12) drives is not active.

Going into storage manager it appears it doesn’t recognize drive 6, and it’s not lit up green on front of unit.

My first question is, has anyone seen a similar issue? Not sure if it could be a glitch from migration or if the drive truly did fail during the migration, though it was healthy before.

My second question: the (presumably) failed drive is a seagate st8000vn0022 8TB. In terms of replacement, am I safe to choose an 8TB from the synology compatible list or should I try to get the exact same drive that it currently is?

I appreciate the knowledge of this community!
